|Patent ID||GB201518717D0 and WO2017068032A1|
A method is provided for forming cross-fades between audio files, which includes providing a plurality of audio files, each audio file comprising a plurality of respective audio streams pertaining to a single song, and providing a library of different fades, wherein each fade defines a respective characteristic shape of change in playback level over time to fade-in or fade-out an audio stream. The method further includes associating a respective fade, selected from the library of fades, with each audio stream, such that a cross-fade from a first one of the audio files to a second one of the audio files can be formed by applying the respective fades of the audio streams of the first audio file to fade-out the first audio file, and simultaneously applying the respective fades of the audio streams of the second audio file to fade-in the second audio file. These fades might be placed intelligently through real-time analysis of the plurality of audio streams and matching of musical features such as harmony. The method can enhance the ability of a content producer to generate musical content that can be changed as desired by a listener, by means of the cross-fade, to reflect, e.g. different preferences, moods or environments.
